HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 390,194, dated September 25, 1888.

Application filed August 24, $86. Serial No. 211,711. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM VOGEL, of Chicago, in the county of Cook and State of Illinois, have invented certain new and usefulv Improvements in Heating Devices; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

to which form a part of this specification.

A heating apparatus embodying my invention comprises as its main feature of novelty a fireplace or other equivalent space or chamber provided with an exit-flue for products of [5 combustion, a burner for gas, vapor, or oil located at the bottom of said chamber, and a thin metal plate, sheet, or shell located in the said chamber in such manner as to form a radiating-surface exposed to the air of the apartment in which the heater is located, the said plate, sheet, or shell being located over the burner in such manner that the flames therefrom shall pass immediately over and in contact with the said metal plate, sheet, or shell, whereby thelatter will be maintained at a red or white heat and will thereby present an agreeable appearance of a glowing or incandescent body present in a coal fire, but absent in gas or oil heating apparatus as heretofore 3o commonly made.

Another feature of my invention comprises a metal plate or shell which is heated by the passage over it of the flames from agas, vapor, or oil burner, and which is made with promi- 3 5 nences or projections, making the metal of the plate thicker in some parts than in others, so that when the plate or shell is heated to a sufficient extent the thinner parts will appear red or incandescent and the thicker parts of darker color or black, according to the relative thickness of metal in the different parts of the cast ing, the said projections or prominences preferably being arranged to form an ornamental figure or design, which will appear in darker shades upon the glowing body of the heated plate or shell. The exterior or visible surface of the plate'or shell will be made smooth, and the prominences or projections forming the figure or design will be made upon the rear or concealed side thereof, so that the figure or design will be visible only when the plate or shell is heated. One desirable form of oil-burner'for use in connection with a plate or shell of the character above described is herein shown, such burner being similar to one shown and claimed in a prior application, Serial N 0. 210,041 filed by me in the United States Patent Office August 5, 1886, certain novel features of construction in the said burner, whereby it may be more advantageously employed in connection with a plate or shell of the character abovedescribed, being shown and made the subject of claims herein.

In the accompanying drawings, Figure 1 is 6 a front elevation of a fire-place heater embodying my invention, a part of the front wall thereof being broken away to show interior parts in section. Fig. 2 is a central vertical section of the same,taken upon line x 00 of Fig. 3. Fig. 3 is a sectional plan view taken upon the horizontal line :10 m, Fig. 1. Fig. 4 is a fragmentary front elevation ofa fire-place heater, illustrating a modified form thereof. Fig. 5 is a similar view, slightly differing from that shown in Fig. 4-. Fig. 6 is a sectional view through a fireplace, illustrating a burner generally similar to that shown in Fig. 1 in connection with a different form of shell. Figs. 7, 8, and 9 illustrate an ornamental appearance which may be given to the front face of a sheet or shell heated to redness by means of suitably-shaped projections upon the rear surface of the said sheet or shell. Fig. 10is a detail section illustrating the air-inlet valve of the burner.

In the said drawings, A indicates a metal plate or shell, B a burner located beneath said plate or shell for heating the latter, and C a fire-place in which the parts mentioned are closed at its bottom, with the exception of an opening, D, for the admission of air to the burner, which opening is provided with a valve, d.

E is a box or shell located within the casing D and supported above the bottom of the latter by lugs c, said box E being open at its top and closed at its bottom.

F is a shallow box or pan sustained by legs IO ffrom the bottom of the shell E, and G is a bottomless shell or frame sustained over the pan F, with its lower margins above the bottom of said pan, preferably by lugs 9 upon the frame resting upon the said pan.

H is a verticallyperforated bed filling the lower open end of the shell or frame G.

I is a cast-metal deflectingplate sustained within the upper part of the casing or shell G, with its lower edge near the top of the bed H, said casting being provided at its top with an outwardly-extending flange, 1, which rests at its outer edge upon the top of the outer box or shell, D, and closes the space at the top of the burner between the casting I and the said box or shell.

J is an oil-supply pipe, which is herein shown as extending horizontally beneath the floor of the room in which the burner is situated to a point beneath said burner, and which extends upwardly through the bottom of the casing D and box E and is secured in the bottom of the pan F.

The burner comprising the parts above described operates in the same manner as does the burner described in the said prior application, the oil from the pipe J entering the pan F and rising through the perforated bed II, while the air admitted through the opening D rises through the space between the side walls of the parts D and E, and then passes downwardly between the frame G and the deflecting-plate I to the upper surface of the bed H, where combustion takes place, the flames rising through the central space or opening formed within the deflecting plate I. Thelower edge of the deflecting-plate l is arranged above the top margin of the pan F, so as to allow the overflow of oil over the top of said pan beforeit rises sufficiently high within the frame G to cut off the passage for air between the said lower edge of the deflecting-plate and the top of the perforated bed, as fully set forth in the said prior application.

In Figs. 1, 2, and 3 is shown a hollow globe or spherical shell, A, which is sustained over the burner B in such manner that its lower surface forms with the flange I of the deflecting-plate I an annular exit-passage, 2', through which the flame from the burner issues at all sides of the shell, the parts being so arranged that the sheet of flame issuing from the passage i passes upwardly over the outer surface of the shellA, the smoke and products of combustion passing away through the exit flue C of the fireplace, which flue is arranged above the top of the spherical shell, so that the flame will be drawn or carried by the chimney'draft over the top surface-of the shell or a greater part thereof.

The shell A in the figures referred to is made vertically movable to enable the width of the passage i to be increased or decreased, and the size of the heating-llame thereby changed as desired, and for this purpose said shell is sustained by means of a rigid stem,K, preferably constructed to slide vertically in a stationary tubular guide'standard, K,located in the rear part of the fire-place. Suitable means are provided for moving said stem vertically and holding it in its changed posit-ion, whereby the shell may be raised and lowered as .desired. The device for this purpose illustrated and preferably employed consists of a horizontal shaft, K provided with a gear-pinion, k, intermeshing with a rack, is, upon the stem K, the said shaft being provided upon its outer end with a hand-crank, K, whereby the shaft may be turned. Any suitable means may be employed for locking the shaft from movement, that herein shown consisting of a movable pin, k adapted for engagement with either one of a number of holes It", in a stationary segment, K.

The valve d, Fig. 10, controlling the air-iir let opening I) of the burner, preferably consists of a plate attached to the shaft K and so arranged that when'the shaft is turned in a direction to lower the shell A, and thereby close the passage i,the said valve will be closed, and when the passage '5 is opened bya reverse movement of the shaft thevalve d will be similarly opened. By this means the air-inlet opening will obviously be controlled to sup ply the quantity of air necessary for a large or small flame without requiring any special attention by the operator to secure this end.

The fire-plaeeshown is provided with an ornamental front piece, G", and with a horizontal bottom plate, C, upon which the burner It is sustained, and which forms the bottom of the box I). The shaft K is located beneath said bottom plate, and the front piece, is provided with openings 0 to admit air below the plate to the inlet-opening D of the burner.

A. A, Figs. 1, 2, and 3, are wings or shields placed at the sides of a shell used in a fire place to deflect the sheet of flame passing from the rear part of the passage t to and over the front or visible part of theshell. The shell, furthermore, is provided with an opening, a, in its bottom over the central opening of the burner and a second opening, a, in its top. When the shell is lowered and the valve (Z closed to extinguish the bnrner'flame, the gas or vapor thereafter generated from the oil then contained in the heated porous bed H passes upwardly through the said openings and burns at the top opening, a, until all of such gas or vapor is consumed. Apart of the flame from the burner will commonly pass into the interior of the shell A through the lower opening, (1, thereby facilitating the heating of the shell.

The shell A (shown in Figs. 1, 2, and 3) is shown in Fig. 2 as provided in its front part with prominences or projections a a upon its inner surface. The main part or body of the shell will be made sufficiently thin to become heated to a red or white heat by the flame passing over it; but the said prominences or projections, being thickeigwill become heated to a less degree, and will therefore afford dark figures upon the glowing surface of the shell when the latter is heated. The appearance of the shell, in which the said prominences are made in the form of a central boss and an encircling ring when the shell is heated,is shown in Fig. 1. Ornamental designs of any kind may obviously be made by giving suitable shape and thickness to the prominences, as illustrated, for instance, in Figs. 7, 8, and 9.

A metal plate or shell'adapted to be heated to redness by the burner-flame in the manner above described may be of other than spherical shape and may be irregular instead of symmetrical in form. In Figs. 4 and 5, for instance, I have illustrated a metal shell shaped to imitate a number of pieces of wood piled together and a pile of coal. case will preferably be made with openings or perforations a, Fig. 5, to allow the passage of the flame through and over all parts of the irregularly-shaped shell. In the use of a shell of this kind a natural appearance of the ebjects imitated may be more closely obtained by varying the thickness of the metal of the shell, so that portions thereof shall appear dark,while others are heated to redness or to a state of iucandescence, as above set forth.

In carrying out the general features ofthe invention, as above set forth, it is entirely obvions that the flame for heating the shell maybe applied either inside or outside of the latter,or to both the inside and outside thereof. A construction is illustrated in Fig. 6, for instance, in which the central flame-exit opening, 1', of the burner B is connected with the interior of a shell, A, theproducts of combustion passing from an opening, a at the top of said shell. The shell shown in said Fig. 6 is generally flat in form with a rounded outer surface; but a shell thus heated may be otherwise made in practice as found convenient or desirable.

A burner of the character herein illustrated is of especial advantage for use in connection with a plate or shell in the manner herein de scribed, and certain features of construction in said burner, whereby it may be conveniently applied for heating said shell, are therefore herein claimed as part of my invention.

It is to be understood that my invention, as it relates to a plate, sheet, or shell provided with prominences or projections forming ornamental designs thereon, may be employed in connection with a gas or vapor burner, or any other kind of heating device adapted to retain such plate, sheet, or shell at a red or white heat.
